Abstract

An x-ray radiation stabilization system is provided including an x-ray tube (20) which emits x-ray radiation (22). The x-ray tube (20) has an anode (52), a cathode (50), and a vacuum envelope (54) which houses the anode (52) and the cathode (50). A high-voltage generator (40) is connected to the x-ray tube (20). It supplies a high-voltage electric potential between the cathode (50) and anode (52) such that an electron beam flows therebetween. The electron beam strikes the anode (52) producing the x-ray radiation (22). A reference radiation detector (60) samples a representative portion of the x-ray radiation (22) emitted by the x-ray tube (20) and generates a signal in response to an intensity of the sampled x-ray radiation (22). A feedback circuit (80) is connected between the reference radiation detector (60) and the high-voltage generator (40). The feedback circuit (80) generates an error signal and in response thereto directs the high-voltage generator (40) to adjust the high-voltage electric potential supplied to the x-ray tube (20) so that in the x-ray radiation (22) ripple having a predetermined frequency range is substantially cancelled. <IMAGE>
